Note that all values specifying length, distance, size, etc. are in "twips",
twenty units per pixel. That's pretty much arbitrary, though, since the player
scales the movie to whatever pixel size is specified in the embed/object tag,
or the entire frame if not embedded.

Ming offers a number of advantages over the existing
PHP/libswf module.
You can use Ming anywhere you can compile the code, whereas libswf is
closed-source and only available for a few platforms, Windows not one of
them. Ming provides some insulation from the mundane details of the SWF
file format, wrapping the movie elements in PHP objects. Also, Ming is
still being maintained; if there's a feature that you want to see, just
let us know at » http://www.libming.org/.

Ming was added in PHP 4.0.5.
